ABSTRACT
Functional magnetic resonance imaging (fMRI) today acts as the basis for neuroimaging in cognitive neuroscience. Advances inscanner technology, image acquisition, experimental design, and analysis methods collectively push fMRI much ahead. The fMRI allows seeing activity in the brain in relation to the performance of particular behaviours as well as it measures change in blood flow related to neural activity in the brain. It produces a steady increase in the amount of research on cognitive behaviour. One of the major clinical applications of fMRI is in the diagnosis of Schizophrenia. Because of its close ties to neuroscience, fMRI has been widely used since its invention to investigate the neuralbasis of mental illness. Most of the major illnesses, e.g. schizophrenia and major depression, appear to represent disordered neural systems widely distributed in the brain. FMRI provides a means to assess the neurobiological theory that schizophrenia is caused by abnormal frontal–temporal lobe connections. In this paper we provide a review on functional Magnetic Resonance Imaging, the analysis of fMRI data, from the initial acquisition of the raw data to its use in locating brain activity, Methods, Tools Techniques used, their advantages, Disadvantages making inference about brain connectivity and predictions about psychological or disease states.
